if you have access to a costco a lot of people like the kirkland plain white tees i have a bunch theyre cheap in packs and a bit heavier and longer than many white shirts which makes it clear that theyre not really undershirts hopefully itll let you spend full price for a pair of shoes that you like generally people prefer not to wear secondhand vans and maybe a couple of other pieces that you really like and arent cheap like a jacket or something
